RADIATOR.

Application filed November 8, 1920. Serial No. 422,632.

To all @072 am it may concern.

Be it known that I, AUGUST KEHM, a citizen of the United States, and resident of Chicago, county of (look, and State of Illinois, have invented certain new and useful Improvements in Radiators, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

The invention relates to radiators and has for its object to provide a. radiator of increased efliciency witha view to reducing the weight and fluid contents in proportion to heating capacity. While it has been recognized that the mounting of radiators in upright position is desirable to secure rapid movement of the surrounding air over the heating surfaces of the radiator, it is also known that the advantages of this arrangement are only partially obtained in practice because of the fact that air which is warmed by contact with the lower portions of the radiator does not rise in close proximity to the heating surface throughout the full height of the radiator, but moves upwardly and outwardly away from the radiator in the intermediate portions of the same.

The present invention accordingly contemplates an upright radiator having vertical fines which preferably extend throughout the major portion of the height of the radiator and which serve to receive and confine a substantial part of the air rising about the radiator. Contact of the air so confined with the heatin surface of the radiator throughout the full length of the fines is thereby insured with the result that warm air is discharged from the fines into the room at both a high temperature and high velocity. Furthermore, as the movement of air over the heating surface is stimulated by the vertical arrangement of the fines, the radiator becomes more efiicient and both the heating surface and fluid contents may be reduced.

In the accompanying drawings Fig. 1 is a detail side elevation of a radiator embodying the features of improvement provided by the invention;

Fig. 2 is an end view of the same partly broken away and with one of the radiator columns removed and the top and bottom headers shown in section, and

Fig. 3 is a lan sectional View taken on the line 33 of I ig. 2.

The invention is illustrated as applied to awall radiator of the type forming the subject of my patent on radiator, No. 1,383,72t, granted July 5, 1921 the same comprising top and bottom headers 10, 11, and upright columns 12 connecting the headers. In this particular type of wall radiator the columns 12 each have one straight side 13 which lies in the same plane with the adjacent side of the headers and an offset side 14 which projects beyond the headers.

In carrying out the present invention the columns 12 are preferably less numerous than is usual in radiators of similar size. The drawings show the columns 12 arranged along the headers 10, 11, with relatively wide spaces 15 between adjacent columns. Since the chambers, as 16 (Fig. 3) of the columns 12 provide the principal part of the fluid capacity of the radiator while the walls of the columns represent an important part of the weight of the radiator, the reduction of the number of columns affords a substan tial reduction in both the fluid capacity and the weight of the radiator.

On the other hand the relatively wide spacing of the columns 12 provides room between the columnsfor vertical flues 17. As shown, the lower ends of these fines are located just far enough above the bottom header-11 of the radiator to provide a free opening for the entrance of air into the fines while the upper ends of the fluesare located only a'short distance belowthe top header 10. Air entering the spaces 15 between the columns 12 at the-bottomjof the radiator is accordingly confined in its upward travel until it reaches the top of the radiator where it is discharged into the room at relatively high velocity.

In order that the walls of the fines 17 may constitute a part of the heating surface of the radiator they are preferably constructed to make contact with the walls of the adjacent columns 12 at each side over a substantial area. In the construction illustrated this is accomplished by forming the fines 17 from sheet metal and of such size that elastic distortion of the fines is required for their introduction between the columns. Under these circumstances, each flue 17 is forced between two adjacent columns 12 and makes a wide contact with the column at each side throughout the length of the flue, as at 18 and 19 (Fig. 3). Furthermore,

12 and is also to be regarded as a part of the heating surface of the radiator.

ll hile the employment of the particular style of wall radiator illustrated in the drawings is not essential, its use is advantageous as it permits of the extension of the lines 1''? in front of the upper header 10. 'lhe discharge of heated air from the upper ends of the fiues is thus largely directed outwardly into the room as indicated by-the arrows at the upper part of Fig. 2'.

When the columns 12 and headers 10, 11 are of cast iron, as shown, the sheet metal flues 1'? are conveniently applied after the cast iron portions of the radiator have been erected at the place of use.

Under the circumstances the elastic expansion or" the walls of the fines against the adjacent columns may be supplemental, if desired, to avoidaccidental displacement of the fines and insure good contact or" the walls of the lines with the heating columns, by the introduction of clamping screws through the fiues for compressing the walls of the fluesin the direction ofthe depth of the radiator. be as numerous as required in accordance with the height of the radiator and the stiffness of the walls-of the fiues, each flue being provided with two such clamping screws in the particular construction illustra-ted in the drawing.
